G O V E R N O R SPECIFICATION forming part of Letters Patent No.578,238, dated March 2, 1897.

Application filed June 29,1896. Serial No. 597,500. (No model.)

To all whom it may concern.-

Be it known that I, ALLEN OTIS HANEY, a citizen of the United States,and a resident of Milford, in the county of Kosciusko and State ofIndiana, have invented certain new and useful Improvements in Governors;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which .will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawing, which forms a part of this specification.

My invention relates to governors principally designed for use inconnection with pumps for pumping water or compressing air;

and its object is to provide an improved construction whereby when theair or water reaches a certain predetermined pressure in the tank orreservoir in which it is pumped or compressed the pump will ceaseoperation and when the pressure is normal the pump will be again set inoperation automatically. The pump will thus be alternately stopped andstarted as the pressure in the tank increases or diminishes, so that acontinuous and uniform pressure will be maintained in the tank.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawing the figure represents a longitudinalsectional view of a governor constructed according to my invention.

In the said drawing the numeral 1 designates a cylinder in which islocated a piston 2, provided with a piston-rod 3, which passes through astuffing-box 4 in the upper end of the cylinder and is connected withthe shifting-bar of a clutch mechanism by a beltshifter or other meansfor throwing the pump into and out of operation. At each end of thecylinder is avalve-chamber 5 and 6, connected together by a verticalpipe 7, and communicating with these valve-chambers is a port 8 and 9 atopposite ends of the cylinders. Located in these valve-chambers areordinary slide=valves 10 and 12, each having an exconnected together bymeans of a valve-rod l5, and so located thereon that when oneis open theother is closed.

Connected with the upper valve-chamber 5 is a small cylinder 15, inwhich is located a piston 16, secured to the valve-rod. The upper end ofthis cylinder is closed by means of a screw-cap or cover 17, providedwith a central screw-threaded opening 18, through which passes ascrew-threaded tube 19, provided with a head 20. The valve-rod passesthrough and works in this tube, and confined between the inner end ofthe tube and the piston 16 is a coiled regulating-spring 21. Thevalve-chamber5 is provided with an opening 23, connected by a pipe (notshown) with a closed tank or reservoir, into which water or air ispumped or compressed by the pump.

The operation is as follows: In normal condition the valve 10 is closedand valve 12 open by the pressure of the coiled spring, and the piston 2is at the upper end of the cylinder 1, being elevated to this positionby the pressure of the water or air in the closed tank or reservoirwhich will escape therefrom through the lower valve 12 and its port letinto the said cylinder below the piston. In this position the pump willbe thrown into working or operative condition. hen the pressure in thetank reaches a certain predetermined degree, which is regulated by meansof the tube 19, the tension of the spring will be overcome and thepiston 16 elevated, raisingthe valve-rod and opening valve 10 andclosing valve 12. The air or water will now enter the upper end of thecylinder 1, depressing the piston 2 and exhausting at the lower end ofthe cylinder. This movement of the piston and piston-rod will stop theworking of the pump until the pressure in the tank decreases or fallsbelow the desired degree, when the tension of the spring will reversethe valves and again throw the pump into action. This operation will berepeated alternately, so that a uniform pressure will be maintained inthe tank.

Having thus fully described my invention, what I claim is-- Thecombination with the cylinder having a port at each end, the pistonlocated therein, the piston-rod, the valve-chambers communieatingtherewith, one of which is provided with an opening adapted to beconnected with a closed storage-tank, the slide-valves and the valve-rodto which they are secured, of 5 the cylinder connected with one of thevalvechainbers, the piston located therein and secured to the valve-rod,the screw-cap having a central screw-threaded opening, the tube engagingtherewith through which the Valverod passes, and the coiled spring;substan- 1o tially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.

ALLEN OTIS HANEY. Witnesses:
